Zcash is a cryptocurrency aimed at using cryptography to provide enhanced privacy for its users compared to other cryptocurrencies such as Bitcoin. The Zerocoin protocol was improved and transformed into the Zerocash system, which was then developed into the Zcash cryptocurrency in 2016. Development of protocol improvements and the reference implementation is led by the Zerocoin Electric Coin Company, colloquially referred to as Zcash Company. The founder and CEO of Zcash Company is Zooko Wilcox-O Hearn. Its founding team includes cryptographer Matthew D. Green from Johns Hopkins University. Roger Ver was one of Zcash Companys initial investors.
Zcash faucets are a reward system, in the form of a website or app, that dispenses rewards in the form of a zatoshi, which is a hundredth of a millionth ZEC, for visitors to claim in exchange for completing a captcha or task as described by the website. There are also faucets that dispense alternative cryptocurrencies. Rewards are dispensed at various predetermined intervals of time. Faucets usually give fractions of a zcash, but the amount will typically fluctuate according to the value of zcash.
Faucets are a great way to help introduce new people to zcash, or to your favourite altcoin. Many faucets provide information to newbies as well as offering them some free coins so that they can try before they buy, experimenting with a test transaction or two before putting real money on the line. Since this whole area is so new and a bit scary to some people, who perhaps dont quite trust it with their hard earned cash yet, this is a great way to promote digital currency and bring in new users.
